Control Circuit Terminals
Symbol
Input
S1
Output
Name
Forward/Stop
Function
Forward at ON. Stops at OFF.
S2
Multi-function input 1 (S2)
Set by parameter n36
(Reverse/Stop)
S3
Multi-function input 2 (S3)
Set by parameter n37
(Fault reset)
S4
Multi-function input 3 (S4)
Set by parameter n38
(External fault:Normally open)
S5
Multi-function input 4 (S5)

(Multi-step reference 1)
SC
Sequence input common
Common for S1 through S5
FS
Frequency reference
power supply
DC power supply for frequency
reference use
20 mA at 12 V DC
FR
Frequency reference input
Input terminal for frequency
reference use
0 to 10 V DC
(input impedance: 20 kΩ)
FC
Frequency reference common Common for frequency
reference use
MA
Multi-function contact output
(Normally open)
MB
Multi-function contact output
(Normally closed)
MC
Multi-function contact output
common
Common for MA and MB use
AM
Analog monitor output
Set by parameter n44
(Output frequency)
AC
Analog monitor output
common
Common for AM use
Note
Set by parameter n40
(during running)
Signal level
Photocoupler
8 mA at 24 V DC
Note NPN is the default setting
for theses terminals. Wire
them by providing a common ground. No external
power supply is required. To
provide an external power
supply and wire the terminals through a common
positive line, however, set
the SW7 to PNP and make
sure that the power supply
is at 24 V DC ±10%.
Relay output
1 A max. at 30 V DC
1 A max. at 250 V AC
2 mA max. at 0 to 10 V DC
1. Depending on the parameter settings, various functions can be selected
for multi-function inputs and multi-function contacts outputs.
2. Functions in parentheses are default settings.
Selecting Input Method
Switches SW7 and SW8, both of which are located above the control circuit
terminals, are used for input method selection.Remove the front cover and
optional cover to use these switches.
